Definitions

  • This invention relates to an apparatus for use a method for raising piglets where one or more piglets are dried immediately after birth.
  • Newborn piglets are covered with amniotic fluid.
  • the amniotic fluid leaves a fibrous layer of skin that is then removed by contact between the animal and its environment. Until it is completely removed, this skin makes the complete drying of the animal very difficult.
  • a wet piglet loses a lot of energy to maintain its body temperature during the evaporation process and often weakens to a point where it struggles in its search for the nipples. It is very important that each piglet feeds as early as possible after birth to receive an appropriate amount of colostrum which plays a very important role in its early development. In fact, colostrum promotes proper development of its immune system, not to mention it also provides energy.
  • an apparatus for using in raising piglets comprising:
  • a container shaped and arranged for receiving one of more piglets; the container having an opening arrangement for insertion of said one or more piglets to be confined within the container; the container having an air movement system and optionally heating system for applying drying air to said one or more piglets within the container sufficient to cause drying of the piglets from the wet condition;
  • the container being arrange to maintain said one or more piglets confined with the container temporarily until substantially dried from the wet condition.
  • An automated drying system of this type can therefore both reduce the number of deaths of piglets who are too weak to survive the above problems and in addition can improve growth even in the stronger piglets who would in any event survive, since they are encouraged by the drying action to start feeding earlier.
  • the piglet is released from the container.
  • the release may be by way of an action of the control system to open a release door or opening or in an alternative simplified arrangement, the piglets may be removed manually by the worker who may also simply manually switch off the drying action.
  • the time period of the drying action may be controlled by a timer which approximates the drying time required or could also be determined by sensor which uses humidity or other parameters to actually detect the amount of drying which has occurred. That is the sensor acts to detect a condition after sufficiently drying the one or more piglets. That is a system without a controller such as with a simple ON/OFF drying switch can also be used in this concept.
  • the drying container in order to provide a drying action within a temporary time period is arranged preferably for optimizing variables to optimize drying air velocity, temperature, humidity.
  • This arrangement can be used in conjunction with a system in which there is provided a compartment at a level below the pen floor in which piglets slide after birth and which protects them until they are ready to return to the pen to access the sow.
  • the piglets can automatically enter the drying device and are allowed to leave only once they are dry.
  • the system can include a detector which operates to start automatically as the piglets enter.
  • the arrangement can include detectors which carry out an analysis of system variables to determine when piglets are completely dry to stop the drying process instead of a timer.
  • the arrangement can include a closed-loop system to manage and optimize the drying process variables (power to heater, fan speed, etc.) in reaction to input variables (temperature, humidity, air speed, etc.) instead of pre-determined conditions
  • the arrangement can include a heat exchanger or air mixer to increase heating efficiency.
  • the container includes an opening closable by a closure member for release of the piglets.
  • the closure member is preferably held closed and the container includes a latch operable on the closure member when the piglets are dried for release of the piglets.
  • the closure member for release of the piglets can be provided at any location on the container such as after one wall, preferably the closure member comprises a floor panel which is hinged at one side and lowered to the floor of the farrowing pen at the end of the drying period to allow the release of the piglet.
  • the container can be located in the farrowing pen at a height spaced from the floor of the following pen so that it is at a convenient height to enable the worker to place the piglets in the container through an upper opening while the piglets are lowered to the ground without damage by the lowering of the floor panel.
  • the presence of the container within the farrowing pen at a height spaced above the floor therefore leaves the floor open for the remaining piglets to take their place on the piglets area without interference from the container.
  • the container includes a radiant heating member for applying radiant heat to said one or more piglets within the container. That is, at the end of the drying cycle the air movement is turned off and the piglets remain in the container while radiant heat is applied. The tendency is for the piglets to be significantly cooled by the air movement and by the convection effect of the drying action while the air movement continues to dry the piglets. The addition of heat to the air as it is blown across the piglets does not significantly increase the drying efficiency or reduce the drying time, it is not necessary therefore that heat should be applied to the air as it is blown across the piglets.
  • the radiant heat can be used during the drying action to try to maintain the body temperature but more importantly the radiant heat is used after the drying is complete to reheat the piglet to raise its body temperature to a normal temperature.
  • the control system which operates the drying action provides a timer which operates the air movement or fan for a predetermined time period, following which the radiant heat is applied for a subsequent time period, following which the closure member, such as the floor panel, can be opened to release the piglet.
  • the radiant heating member is arranged to apply said radiant heat to said one or more piglets in the container after the air movement is halted.
  • the radiant heating member is arranged to apply said radiant heat to said one or more piglets in the container and the air in the air movement is un-heated.
  • the air movement system comprises at least one nozzle arranged for directing air across the container at a height to intersect the piglets on a floor of the container.
  • the air movement provides an airflow across the body of the piglet.
  • the airflow is sufficiently rapid that the air movement is uncomfortable to the piglet in its stage immediately after the so that the piglet tends to move within the container to try to escape the air movement.
  • This movement of the piglet typically asked to turn the body of the piglet relative to the airflow so that the drying action occurs across the full body surface. Therefore without moving the airflow nozzle, a drying action across the full surface area of the piglet come be obtained.
  • nozzles arranged at different heights relative to the floor.
  • the nozzle preferably comprises a slot extending across an upstanding wall of the container.
  • the airflow is provided as two blades of airstream across the container and different heights to dry different areas of the piglet body.
  • the nozzles come be provided in one sidewall, preferably the nozzles are arranged in opposite side walls so as to access the piglet body from both sides.
  • the container includes a perforated floor such that the air movement exits through the floor and acts to dry the floor. Without this drying action on the floor, it is possible that the floor can become wet and slippery with the possibilities for damage to the piglet by falling.
  • the injected into the container therefore escapes after passing over the body of the piglet downwardly through the preparations in the floor to carry the moisture off the piglet and out of the container the container remained dry and clean.
  • While the above arrangements provide a preferable construction for the container which avoids the necessity for both heating of the air and for movement of the nozzle injecting the air into the container, other arrangements may use an air drying action which incorporates heating of the air and movement of the nozzle. Such heating does not necessarily increase the rate of drying nor does it necessarily keep the piglet at a warm body temperature. Depending on the amount of heat applied to the air stream, the air may keep the piglet at a warm body condition, but it is not energy-efficient to do this and hence arrangements of this type are not preferred in the present invention. It is important but not essential that a heating effect be applied to the piglet before release to ensure that it is at a desirable body temperature.
  • a farrowing apparatus for use in raising piglets comprising:
  • the container includes support components or hangers by which it can be mounted in the selected one of the farrowing pens at a position spaced from a floor of the pen and a floor panel of the container is openable to lower said one or more piglets to the floor of the frame arrangements.
  • the worker can carry the container providing the drying action from one pen to another during the birthing process as required.
  • the container can be simply hung over a top rail of the farrowing pen with the top cover panel for the bull by the worker to place the piglet in the container.
  • the floor panel when opened after the drying action lowers the piglets or piglets to the floor.
  • the above arrangement provides a simple construction which uses preferably a timing action for the air movement and for the radiant heat dry out.
  • This arrangement is all they simple mechanical nature where the control uses limited input information.
  • more complicated systems can be developed which use humidity and other sensors for detecting other information to control the drying action. In this way the timing of the drying action can be better controlled to ensure full drying of the piglet or piglets regardless of the number of piglets in the container.
  • the dryer While the dryer is proposed for use generally in farrowing area that is a barn or other area set up for farrowing sows, it is not necessarily mounted directly inside a single farrowing pen or crate but could be placed on top of the stall or at some other suitable location. Obviously, if not located on or at the floor of the pen, this would not allow a door to be opened to simply release and orient the piglets toward the nipples but this feature is not essential.
  • a container is something to contain the piglets and that it can be anything that restricts the piglets from escaping until they are dry.
  • a ventilation and heating system could be installed in a creep assembly with some gates to keep the animals in until they are dry. This is included herein so that the definition of a container is something to "contain”.

  • a heating device can be provided to control the enclosed air temperature and the piglet surface temperature, optimizing the evaporation rate and keeping the piglet comfortable which is an important factor.
  • a simple cold air velocity acts to dry the piglets but it is desirable to ensure that they are comfortable. This would cause a stress which should be avoided. Also, it is important to understand that rising the piglet's skin temperature make sure they don't use their energy to heat up their body to reach a comfortable temperature.
  • a preferred configuration maximizes energy efficiency by having a heat exchanger system or a mixer to pre-heat incoming air with the hot air exhausted from the drying device.
  • a fan creating an air flow in and out of the box is provided to maximize drying. Moreover, the fan is arranged so that the air velocity and turbulence act to break the thin skin layer and thus remove it faster than contact with the environment.

  • the frame preferably consists of a floor on which the animals will stand and at least two walls to enclose the animals and drying environment. The best would be four walls thus fully confining the piglets, but the number of walls can be varied and might change to less and also to no walls.
  • the rate of evaporation can be increased by adding a mixing fan inside the device to increase air speed at the surface of the animal, thus increasing rate of evaporation.
  • an alternative arrangement which reduces worker participation can include a funnel to guide piglets into the box without intervention and automatic control by which, upon sensing the presence of a piglet, the drying components is activated automatically and begins drying the piglets as they enter.
